An exhaust gas dilution device according to an exemplary embodiment of the present invention includes a head part, ejector unit, a nozzle part, and a dilution part. The head part has a space part into which an exhaust gas flows and a through-hole formed through the center axis direction to be connected to the space part. The ejector unit is coupled to the head part and has a first discharge hole formed passing through the center axis direction to be connected to the through-hole and connected to a first inlet to which primary dilution air is supplied. The nozzle part is inserted into a first discharge hole through the through-hole and has a second discharge hole that penetrates in the center axis direction so that the exhaust gas flowed into the space part is sucked and ejected into the first discharge hole as the primary dilution air moves through the first discharge hole. The dilution part has a first flow path part into which a primary dilution gas, which is generated and discharged after the exhaust gas and the primary dilution air are mixed in the first discharge hole, flows, and a second flow path part connected to the first flow path part and guiding secondary dilution air to be mixed with the primary dilution gas, and generates a secondary dilution gas as the primary dilution gas and the secondary dilution air are mixed.

A combustion analyzer system includes an analyzer unit, a primary analysis probe and one or more remote probes. The analyzer unit includes a condensation removal unit and two or more electrochemical sensors to detect at least oxygen and carbon monoxide. The analyzer unit also includes a means for sealing or isolating the electrochemical sensor inputs to prevent oxidation of the reactive elements when the unit is not in use.

A particle detecting module is disclosed and includes a main body, which is consist of an air guiding part and a detecting part, by driving a plurality of heating elements disposed within a plurality of storage chambers of the air guiding part, air inside these storage chambers is heated and the moisture of the air is removed, and then the air is transported to the detecting part, so that a sensor of the detecting part could detect the sizes and the concentrations of the suspended particles, and the interference of the humidity is reduced.

A system for on-stream sampling of pressurized process gas such as natural gas or the like, said system optimized for use with pressurized process gas having liquid entrained therein, or otherwise referenced as wet. In the preferred embodiment, a probe and method of sampling is contemplated to provide a linear sample of fluids from a predetermined area of said fluid stream. Further taught is the method of preventing compositional disassociation of a gas sample having entrained liquid utilizing a probe having a passage formed to facilitate capillary action in fluid(s) passing therethrough. The present system further contemplates a unique modular vaporizing pressure regulator formed to electrically engage a tube bundle via a tube bundle boot mounted on the bracket of a modular sample system in order to dispense with the need for conduit normally required for a separate power cord.
